Specicaton of Letters Patent.

Patented Sept.. 11, 191%'.

Application filed April 13, 1,914, Serial No. 831,397. Renewed March` 253, 1917. Serial No. 156,968. l

To all 'whom z' may concern:

Be it known that I, KENNETH Brunn, a citizen of the United` nStates, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Anchors, of which the following is a specification.

My invention relates to an improvement in anchors, and it has for its object to provide an anchor in which the Vshank is loosely secured in the anchor head, with novel means for securing the shank in place.

This object is accomplished by means of the structure shown in the accompanying drawing, in which- Figure 1 is a plan View of my improved anchor.

Fig. 2 is an end view of Fig. 1.

Fig. 3 is a'bottom plan view of Fig. 1.

Fig t is a sectional view, taken on the line A-A of Fig.P 1.

Fig. 5 is a plan view of a locking element.

Describing the drawing in detail, 1 repre-v sents the anchor head having the flukes la formed integrally thereon, and in the median line between said lukes is formed a transverse opening 5 into which is passed the shank 2.

At each side of theopening 5 is an enlargement 6 adapted to receive the retaining pin or trunnion 41 which is iiXed transversely in the end of the shank, to form a bearing therefor and upon which the shank is free to rock in the expanded portion 3 of its opeging between the sides of the anchor hea In the body of the anchor, at the inner side the opening 6 is further enlarged to form the circular recess 8, forming a shoulder, at diametrically opposed sides of which are formed the stops 12, one at the front and 5the other at the rear side of the opening Transversely of the opening 5 is formed in the bottom of the anchorhead a further opening 5a whose longitudinal or side portions register with those of the corresponding sides of the stops 12 and whose end port-ions register with the outer limit of the shoulder 8. As the shank is inserted into its opening 5 from the lower side of the head 1, the bearing pin 4f will be free to pass through the transverse enlargement 5a into its seat 6.

On placing the shank in position, the trunnion will pass freely through the space or opening 5, into the seat 6, whereupon the plate 7, which conforms to the opening 5a, may be inserted through that opening onto the shoulder 8, where it will rest between the stops 12. This plate may now be rou tated upon the shoulder 8 until each end portion comes against the corresponding stop 12, where it will stand at right angles to vits original position, and directly across the aperture 5. The end portions will thus engage beneath the outer portion of the anchor head and thereby effectually close the aperture 5 and prevent possible dislodgment of the shank.

To prevent retrograde movement of the locking plate I have inserted a screw 11 through the outer casing of the anchor head so as to stand against the free edge of the plate, thereby rendering accidental releas ing impossible. The plate may be rotated by means of a tool inserted through the opening 9.

The body of the anchor is provided in its upper face with a plurality of cavities, as at 1b, leaving an outer shell which may be irregularly shaped and provided with scalloped edges, as shown, or it may be formed in any suitable and convenient design. The purpose of the cavities is to form receptacles into which the silt or muddy deposits into which the anchor is cast may collect and when covering the anchor, it will form with the surrounding deposit, a homogeneous mass, which will produce a strong suction tending to hold the anchor in place.

The apertures 1c leading from each of the recesses to the lower face of the anchor permits the mud to be washed from those recesses as the anchor is lifted from its moorings.

Having thus described my invention, what I claim as new and desire to obtain by Letters Patent, is

2. An anchor comprising a head-piece having a fluke at each end and a shank'opening 1n the head-piece intermediate said iiukes, a. trunnion seat in each, side of the shank opening leading to the bottom face of said head-piece, -a recess formed in the shank opening adjacent the lower outlet thereof, a shank having a trunnion at each side of one end adapted to be inserted from the lower side into said opening, a` plate" adapted to pass within said trunnion seats and to'be rotated within said recess to lool:

`the shank opening, and means for securing Copies of this patent may be obtainedV for ve cents each, 'by addressing Washington, '.D. C. Y Y

side of said head piece than it is through the top side of said head piece, whereby to form a chamber in said head piece, a shank provided at one end with an enlarged portion, said shank being adapted to be inserted upwardly through said head piecerwith its enlarged portion occupying the chamber therein; anda retaining member for closing the bottom of said chamber in said head piece, said retaining memberbeing adapted to be locked in place in said-chamber .by being rotated a partial turn'therein.

In testimony whereof I alix my signature in the presence of two witnesses.
